[PATCH v2 0/2] segtree: move huge arrays to heap

[Oleksandr Natalenko <oleksandr@natalenko.name>]

While dealing with huge sets, nft may exhaust stack
and trigger segfault. To avoid this, lets move those
huge arrays away from stack to heap.

First patch introduces array allocation helper.

Second patch modifies interval_map_decompose()
function, allocating memory for arrays on head.

Meny thanks to Florian Westphal who helped
to sort this out.

Changelog:

v2: nmemb actually can be 0, so remove that
    assertion

v1: initial submission

Oleksandr Natalenko (2):
  utils: provide array allocation wrapper
  segtree: allocate memory for arrays on heap
